YARN-REEL.

SPECIFICATION formng part of Letters Patent No. 409,940, dated August27, 1889. Application filed May 4, 1889. Serial No. 809,636. (No model.)

T0 all whom, it may concern- Be it known that I, EDWARD O. DUFFY, ofPawtucket, in the county of Providence and State of Rhode Island, haveinvented certain new and useful Improvements in Yarn-Reels, of which thefollowing is a full, clear, and ex act description, reference being hadto the accompanying drawings, forming part of this specification.

This invention has reference to an improvement in a yarn-reel, by whichthe adjusting of the skein onv the reel is facilitated and theresistance to the revolution of the reel regulated.

The invention consists in the peculiar and novel construction of theradial arms forming the reel, the disk by which the outer ends of thearms are simultaneously extended to stretch the skein, and the clampingdevice by which the rotation of the reel is retarded, as will be morefully set forth hereinafter.

Figure 1 is a view of my improved yarnreel, showingl the spools on theends of the extended radial arms in solid lines, and the position of thespools when the arms are contracted in broken lines. Fig. 2 is asectional view on awertical line through the center of the radial arms.Fig. 3 is a front view of one of the extension spool-arms, and Fig. 4 isa side'view of the same. Fig. 5 is a sectional view of the clampingdevice by which the frictional resistance to prevent the too freeunwindin g of the yarn from the reel is regulated.

In the drawings similar numbers of reference designate correspondingparts throughout.

The yarn-reel is shown in the drawings supported on the shaft 6,projecting from the upper part of the standard 7 In a hole formed in theboss 8 the shaftis secured and is held against rotation by theclamp-screw 9. The hub 10 is bored out to fit the shaft (i and turn onthe same, the rear portion of the hub 10 being extended beyond the reeland split into two parts by the slit or cut 11. ``Around this split partof the hub 10 the clamp 12 is placed, and is secured to the hub 10 bythe screw 13, so as to rotate with the same. The clamp encircles thesplit part of the hub and is provided with two projecting ends, throughone of which ends the clamp-serew 14 passes and is screw-threaded' intothe other. Byturning 'the clamp-screw 14: so as to bring the two endsnearer together the split hub is contracted and forced against the shaftG, so as to bind on the same and cause resistance to the turning of thereel on the shaft, which resistance can be regulated so as to be justequal to the required tension on the yarn.

The radial arms 15 extend from the hub 10 and rotate with the same.These arms 15 are each provided with the central slot 1G. Theextension-arms 17 are provided at their outer ends with the spools 18.As shown in Fig. 4, these extension-arms 17 are bifurcated, so as toallow theradial arms 15 to enter the slots Both of the sides of the arms17 are provided with the slots 19.

The extension-arms 17 are secured to the radial arms 15 by placing theradial arms into the slots 26, passing a screw through each of thecountersunk holes 20 and the slots 1G in the radial arms 15, andscrewing the same into the t-hreaded holes in .the opposite limbs of thebifurcated arms 17, and fiXing the pins 21 into the radial arms 15, neartheir out-er ends, so as to extend from the same into the slots 10, thussecuring the extension-arms to the radial arms and allowing` the sametoslide on each other, the pins 21, secured in the radial arms, sliding inthe slots 10, and the screws secured in the extension-arms sliding iuthe slots 16 of the radial arms.

Mounted loose on the hub 10 is the circular plate 22, provided with thecurved slots or ways 23. The bolts 24= are each provided with a headthat bears against the rear face of the plate 22. They pass through thecurved ways 23, through the hole 25 in each one of the limbs of theextension-arms 17, through the slots 01` ways 1G in the radial arms 15,thence through the outer hole 25 in each of the other limbs of theextension-arms 17, and have the outer threaded ends each provided with athumb-nut, as is shown in Fig. 2. Each of the bolts 24 may be providedwith a thumbnut, so that all the arms may be secu red firmly to theplate 22. In practical use I find that if one or two of these bolts 24are each provided with a thumb -nut the rest may be screwed into theouter holes 25 in the extension-arms 17, which holes are threaded forthis purpose. The curved slots or ways 23 act as cams against the bolts24, and as these bolts are secured in the extension-arms 17 the saidarms are made to slide outward or inward simultaneously when the plate22 is turned in one or the other direction, and when any one of the armsis clamped to the plate 22 by the thumb-nnt on one of the bolts 24 theplate 22 is held against rotation independently of the radial arms 15.All the bolts 24 are therefore supported in the curved ways 23 at t-hesame distance from the hub.

The operation is as follows: Vhen the skein or skeins of yarn are placedon the spools or bobbins 18 and the spools or bobbins are to be extendedso as to eXert a strain on the yarn, the plate 22 is turned to the left,while the radial arms are held stationary. By this motion of the platethe curved ways force the bolts 24, and with the same the extensionarms17 outward, until the desired strain is on the skein, when one or moreof the radial arms 15 are clamped to the plate 22 by the thumb-nuts 011one or more of the bolts 24. In running the yarn off from the reel it is(lesirable to have the least possible strain on the yarn and to have theyarn-reel ret'olve exactly as fast as the yarn is taken from the same,but under no circumstances faster. By adjusting the clamp 12 on the hub10 so as to secure the desired frictional resistance the strain on theyarn in unreeling can be adjnsted with great nicety.

I-Iaving thus described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination, with the stand 7, shaft 6,the hub 10, and the radial arms 15, provided with the slots 16, of thebifurcated extensionarms 17 adj ustably secured to the radial arms, theplate 22, provided with the ways 23, and the bolts 24, one or more ofwhich are provided with thulnb-nuts constructed to clamp the arms to theplate, as described.

2. In a yarn-reel, the combination, with the standard and the shaft onwhich the reel re- Volves, of the hub of the reel provided with atubular extension, having the cut 11,cla1np 12, and regulating-screw 14,the whole constructed to regulate the unwinding of the yarn from thereel, as described.
